Two teenage sisters and their boyfriends have been sentenced to life terms with terms of between 22 and 18 years for murdering their father.
Antoni Robinson, 61, was stabbed 15 times by Gordon Harding, the partner of Ashleigh Robinson, as he slept in his bed in Old Colwyn.
The court was told that while Harding stabbed Mr Robinson, a retired antiques dealer and French polisher, the others were “secondary parties” to the murder.
Ashleigh Robinson, 19, and Harding, 20, were convicted last Friday.
Today Harding and Asheligh Robinson were both sentenced to a minimum term of 22 years each.
Holly Robinson was told she must serve 18 years with Roberts serving a minimum term of 20 years.
The four and Joanne Barr, mother of the sisters and Mr Robinson’s former partner of 25 years, were sentenced for conspiracy to pervert the course of justice after lying to police.
Barr was jailed for four years.
At the time of the murder last year Harding was living at Mr Robinson’s house with Ashleigh Robinson and their baby.
The defendants said the only plan was to get jewellery from the house, and there was no plan to kill or hurt him.
The prosecution claimed the Robinson sisters and Roberts had been secondary parties to the murder and that they were part of a plan.
The court heard claims that the killing was the culmination of a tragic family dispute about money, jewellery and property.
Mr Robinson suffered 18 wounds, 15 of them stab wounds, to his face, neck and upper body, including four stab wounds to his back.
